HOG-PEN.

Application filed November 9, 1916.

To all whom it may concern."

Be it known that I, HENRY L. FnRRIs, a citizen of the United States,residing at Harvard, in the county of McHenry and State of Illinois,have invented a new and useful Improvement in Hog-Pens, of which thefollowing is a specification.

Myinvention relates to certain new and useful improvements in hog-pens,and is fully described and explained in the specification and shown inthe accompanying drawings, in which:

Figure 1 is an elevation of the improved pen; Fig. 2 is a section on theline 2 of Fig. 1, showing the guard swung back; Fig. 3 is a section onthe line 3 of Fig. 1, showing the guard in normal position and thetrough elevated; Fig. 4 is a section on the line 4 of Fig. '1; Fig. 5 isan elevation similar to Fig. 1 of a modified construction, and Fig. 6 isa section on the line 6 of Fig. 5.

Referring to the drawings, 7 is a curb, preferably of concrete, to whichare secured in any appropriate manner posts 8 connecttatably mounted arock-shaft 11.

. ends ed by a top rail 9 and having at their lower forwardly extendingbrackets 10 forming horizontalbearings in which 1s ro- Hung from the toprail .9 is a swinging guard comprising a top bar 12, bottom bar 13 andvertical tubes 14. The top and bottom bars 12 and 13 of the guard arepreferably square in cross-section and the vertical bars of the guardare preferably passed through openings in the bottom and top faces ofthe top and bottom bars, respectively, to bear the guard.

against the opposite surfaces of saidbars and the whole guard being heldtogether by bolts 15 passed through certaln of the vertical bars andthrough perforations in the top and bottom bars. This method ofconstruction'is exceedingly simple and convenient, it permits quickassembling and produces at the minimum cost a very r gid guardstructure.

The rock-shaft 11 has secured to its arms 16, bifurcated at their upperends to re ceive pivotally, in holes in their furcations, gudgeons 16 oncollars 1 7 vertically slidable upon certain of the vertical bars of Thefurcations of the arms 16 also receive pivotally between them the lowerend of a pull rod 18 having at its upper end a handle 19 and aguide-ring 20 which surrounds the corresponding vertical Specificationof Letters Patent.

bar of the guard. In the structure herein illustrated two arms 16 withtheir connections are'inounted upon the rock-shaft 11. They bothnecessarily move together, and are employed in the duplicate relation tosecure even application of force at both ends of a comparatively longguard.

The guard is normally held in its outward or closed position by a hook21 which engages the rock-shaft, as shown in Fig. 4, and which can bepulled up to release the guard by means of a button 22 running in a slotin the upper end of one of the Vertical bars of the guard and connectedby a rod or wire with the hook 21.

23 is a feed trough which is made of metal and is pivoted to brackets 24secured to the curb so that it can be swung from its lowered position,as shown in F ig. 2, to the elevated position, shown in Fig. 3. When inuse it occupies the lowered position and it is swung up to dump most ofits contents, and to take a position where it can readily be washed out.The trough is held in its upper position by a hook 25 pivoted to abracket 26 on one of the vertical bars of the guard. The hook has anupward extension formed into an oval ring 27 surrounding the verticalbar of the guard and permitting the requisite play to the hook, while atthe same time furnishing a very secure support for the hook upon thebar;

The operation of the preferred device so far explained is relativelysimple. It is found in practice difficult to handle hogs while thetrough is being filled, not only because the trough is normally insideof the pen and inaccessible, but because the hogs crowd and push intothe trough while it is being filled. The pivoted guard here shownobviates this difficulty. Before feeding the hogs the trough is pusheddown into its normal or lowered position, the button 22 is operated toraise the hook 21 and free the guard and the guard is then swung intothe position shown in Fig. 2 over the trough, so as not only to keep thehogsfrom the trough, but to make the trough readily accessible fromwithout the Jen. As the 'uard swin s b O dead center and, of course,lock the guard firmly in its inner position. Thetrough is then filledand the guard swung back by pulling up on the handle 1;) which raises-inby the foot of'the operator. In the former case, the button by whichthe locking hook 21 is controlled is within easy reach of the operatorwho is at the same time holding the handle 19.

. out as hereinbef-ore indicated.

The preferred form of construction having the rock-shaft and theduplicate bracearms 16 is the more desirable where the pen is a largeone and the guard is therefore of considerable length. The pressurewhich a hog exerts against the guard in trying to get at'the food in thetrough may be very heavy andiwi th a long guard it is important that itbe braced inward at two points near the ends so that a twisting forcecan not be set upon it. When 2111361118 smaller, however, and 'a shorterguard can be used, the balanced bracing is of less importance and thesimpler structure of the modified form can be adopted.

Referring now to Fig. 5 the construction is precisely the same as thatshown in the other figures, except that there is onlya single arm 16,this being pivotally mounted upon a central bracket 28 on the curb. Theoperating-handle for the brace 16 is omitted in this form ofconstruction and the guard is locked in its normal position by a hook 29pivoted to its bottom bar and engaging a laterally extending pin 30 onthe arm '16 and extending 'sufiiciently forward therefrom that it can beoperated by thefoot. This structure is operated, in general, the sameway asthe preferred structure but with this difference.

1 The guard is released by raising the hook 529, commonly by the-toe ofthe operator and the guard is then pressed in either by hand or by thefoot of the operator resting on its bottom bar or on the arm 16. \Vhenit is desiredto return the guard to normal posi' tion the arm is simplyswung up either by the toe of the operator or'by hand and the guardswings shut principally bygravity.

I realize that considerable variation is possible in the details of thisconstruction without departing from the spirit of my in vention;therefore I do not intend to limit myself to the specific form hereinshown and *described B P Pointed out the 01 state of the art.
